Question about adding a hard drive to a SATA box.

I have a SATA Hd in one of my computers. It's the only one in that particular pc. I have a spare IDE hd that I would like to add. Are there any "issues" I should be aware of in doing this, given that none of the IDE channels are presently in use? Do I set it as master or slave, etc....

Well I added the IDE hdd. I moved the DVD burner as a secondary master and put this one on as primary master and it seems to work fine.
It still boots fine from the SATA drive.
Thanks again for your help.
